....rise in the price of a tin of tuna. A particular implication of metastability is that the behaviour of individuals cannot be represented by utility maximising software agents. The dominance of interaction among the agents amounts to social embeddedness in the sense of Granovetter [9] and Edmonds [10]: the behaviour of individuals cannot be explained except in terms of their interaction with other individuals known to them. Dissipation in a social system, analogous to the dissipation of grains of sand in the sandpile model, equates to individuals being influenced by other individuals without ....

....and their temporal direction. One model may be for the prediction of events (forwards) and another for explanation of events that have already occurred (backwards) some will be metaphors for use in thinking about situations (abstract) For a more formal definition of such embedding see [9]. and others will be bald data models of some aspect of the real world (concrete) In figure 1, I illustrate this categorization of some models on these two axes.

....evolutionary process by its (high level) phenomena, then one would no longer a theory but just a description. To illustrate this case I present a computational model, where a memetic process appears to be occurring, but isn t. It is analysed elsewhere in detail for some of its other properties in [9, 10]. It requires some detail of the model set up to be understood for the relevance of the example to be become clear. 4.1 The Extended El Farol Bar Model This model is based upon Brian Arthur s El Farol Bar model [2] but extended in several respects, principally by introducing learning and ....

A detailed account of terms used in the field of new or alternative AI can be found in [18] and [21] Detailed accounts of these interactions as well as general information on the emergence and architecture of believable agents developed within the Oz project can be found in [2] 3] 4] ....

In figure 4 the attendance patterns of the agents during the runs is shown. Figure 4. Attendances (grey=went, black=stayed at home) This seems to be fairly stochastic with some specialisation between agents, but is more accurately described as a version of globally coupled chaos [6] In figure ....

....the case that just because these agents are competing that they ignore each other. Such a co evolution of strategy (when open ended and resource limited) can result in the intensive use of the actions of others as inputs to their own deliberation, but in a way that is unpredictable to the others [6]. So that the suggested structure for agent free will can include a high level of social embedding. 8 Structuring the development of free will within a society of peers The final difficulty is to find how to structure this mental evolution so that in addition to maintaining the internal ....

....of communication between traders before each session of buying and selling. The details of the traders and their interactions can be found in [6, 7] but they are not critical here. What is important here is that it provides: an environment that is beyond the capacity of agent to completely model [8]; that displays distinct phases to which learning heuristics might apply; and that is tunable in the level and type of learning difficulties it presents. To give an idea of the level of difficulty, figure 6 shows a typical example of the price series that the agent is trying to learn. Although it ....
